Second Stage

QMD-S21

Product Detail

Parallel flow type two-stage regulator, neutral buoyancy design, reduce the burden of mouth;

Main material: POLYCARBONATE, ABS plastic steel, unique silica gel material secondary head panel, RK2 grade dark anodized alumina cover ring, effectively prevent secondary head collision wear; Large drainage valve panel design, divers even wearing heavy gloves can easily perform drainage skills; The gas flow can be adjusted according to the diver's breathing ease, which can meet the personal breathing requirements and save the gas margin; T-type extended exhaust valve extends both sides of the design, while increasing the exhaust volume, control the exhaust bubble escape Angle does not affect the line of sight of divers; Ergonomic silicone bite, soft jaw guard easy to contain without fatigue.

● Type: downstream two-stage head regulator.

● Medium pressure: 150 PSI.

● Suction impedance: 1.2-1.4 CIW(water column inch)

● Exhale impedance: 1.1CIW (water column inch)

● Working flow: 2200L/MIN (air supply: 3000 PSI/206BAR).

● Can adjust the size and direction of air flow

● Standard two-stage diving head regulating low pressure tube length: 75 cm / 29.5"

● Can be equipped with integrated universal joint, so that the two head 360 degrees rotation, with the user of various angles of action.

● Utility model patent technology - two stage regulator wedge dispersion diversion technology (WDI technology, patent No. : ZL 2021 2 1919144.9), based on the fluid mechanics of dispersion diversion and turbulence perturbation theory, dispersion of strong flow pressure, so that the two stage regulator will not cause continuous air leakage in strong flow.

● Passed CE and RoHS environmental protection dual certification.
